Hi M:
This is something that really should be discussed in session... For now, just know that it all belongs.
See you then,

(what i want him to say)
Dear M,
You're so insightful. It's true, this relationship is meaningful to me as well. Yes, the limits are set in place for a reason - wouldn't it be lovely if we could stretch them a bit? A normal conversation over tea would be delightful....
Warmly,
T
